WATCHMANS TIME-DETECTOR.

EZ-EGIFICATION forming part of Letters Patent No. 510,745, datedDecember 12, 1893.

Application filed December 20, 1892. fi erial No. 455,765. (No modelfi'T aZZ whom it 71mg concern:

Be it known that I, CHARLES \VEINEDEL, a resident of Louisville, in thecounty of Jetfer son and State of Kentucky, have invented certain newanduseful Improvements in W'atchmens 'limeDetectors; and I do herebydeclare the followingto be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it ap-IO pertains to make and use the same.

My invention relates to an improvement in watchmans time detectors,theobject being to construct the device in such manner that it shall beadapted to be operated by the i5 watchman at certain predeterminedintervals of time and so that it cannot be operated until it giveninterval of time shall have expired.

A further object is to construct a watchmans time detector in such amanner that the instrument itself will indicate whether or not it hasbeen properly operated and so that at each operation of the instrumentthe number of the instrument will be recorded at a central oftice.

A further object is to construct the device in such manner that itcannot be tampered with by the watchman.

Vith these objects in view the invention consists in certain novelfeatures of construc- 0 tion and combinations and arrangements of partsas hereinafterset forth and pointed out in the claims.

In the accompanying drawings: Figure 1 is a face view of the device.Fig. 2 is a face view with the casing removed. Fig. 3 is a Viewillustrating the means for stopping the clock movement, and showing theparts in position to operate the signaling devices. Fig.4 is a separateviewillustrating the clock starting mechanism. Figs. 5,6,7, 8 and Qaredetail views. Fig. 10 is a view in side elevation, the casing beingshown in section.

A represents a back or base plate to which the mechanism hereinafterdescribed is attached, said mechanism being inclosed by a casing 13fixed to the back orbase plateA and having a glass front 0 through whichthe indicators can be read. This case is permanently secured to the backor base plate A and is not to be removed by the watchman who operatesthe device, thus preventing the watchman from tampering with the deviceand sending in false signals. A clock movement D is secured to the backplateAand in its structure comprises a wheel or pinion a. adapted tomake one revolution in one hour.

It also comprises a wheel or pinion b adapted to make one revolution in,preferably, twentyfour hours.

Mounted looselyon the shaft a of the wheel or pinion a and adapted to becarried by and rotated with the wheel b,is a disk c,havinga single toothc. A notched disk (Z- is revolubly mounted below the disk 0 and hasproduced in its face a series of numbers from 1 to 7 inclusive, saidnumbers representing the days of the week. The tooth c is adapted tomesh with the notched disk (1 at each revolution of the disk 0, and saiddisk making one revolution in twenty-four hours it will be seen that thenumbered disk (1 will be moved one notch every twenty-four hours.

Secured to the arbor e of the spring 8, is a collar (2 from which anL-shaped arm a projects, the free or bent end of said arm being adaptedto engage pins e projecting from the wheel or pinion a, the clockmechanism being so time that one of the pins e will reach a point overthe shaft of the pinion a at the same time that the free end of the arm6 reaches the same point and thus stop the clock movement. The pins ewill preferably be arranged at diametrically opposite points on saidwheel so that the wheel, and consequently the whole clock movement, willbe stopped once every half hour. It is evident however, that only onepin a may be employed so as to cause a stoppage of the movement onceevery hour,or more than two pins may be employed so as to cause the 0movement to stop oftener than once every half hour. An arm f is securedto and projects laterally and normally slightly upwardly from the arbore. To the outer end of the arm f, a pitman f is pivotally connected, 5which pitman extends downwardly and at its lower end is pivotedeccentric-ally to a disk g, which latter is loosely mounted on an arborg supported by a frame g A sleeve g projects from the center of the diskg and is too adapted to receive the end of said arbor g' the free end ofsaid sleeve being preferably closed and adapted to receive a crank armIt, said crank arm being secured to said sleeve by means of a pin it.From this construction it will be seen that when the disk g is partiallyrotated the spring 6' will be partially wound, through the medium of thearm f and pitman f, and the L-shaped arm a will be carried away from thepins e carried by the wheel or pinion a. When the disk 9 is thuspartially rotated the L shaped arm e will be carried from the pins ofthe wheel a far enough so that the running of the clock movement for ahalf hour will bring it back again in alignment with the pins 6 so thatits engagement with one of them will cause the clock mechanism to stop.From this it will be seen that it is necessary for the watchman tooperate the device once every half hour.

A collar 1' is carried by the disk 0 and adapted to embrace this collaris a hand or pointer i, which registers with figures on a dial 2' Thefigures on the dial will preferably range from one to twenty four, thusrepresenting twenty-four half hours,or, when the device is adapted to beoperated once every hour, the figures will represent twenty-four hours.

A spring j is connected at one end to the shaft or arbor g and at theother end to a pinj' projecting from the frame 9 A gear wheel is isloosely mounted on the shaft or arbor g and carries a pivoted dogadapted to engage a ratchet wheel k secured to the shaft or arbor g, aspring 10 secured to the wheel 7 being employed to retain the dog inengagement with said ratchet wheel. The gear wheel 70 is adapted to meshwith a pinion Z carried by an arbor Z. The arbor Z also carries a spurwheel 1 which meshes with a pinion Z carried by an arborl. The arbor Zalso carries an escapement wheel Z with which an escapement pawl lengages, said escapement pawl having a weighted arm Z secured thereto toinsure its proper operation. A disk in is secured to the arbor Z and isprovided-on its periphery with teeth or projections m. An insulatingblock m is secured to the frame g and to this insulating block a springa is secured and adapted to be engaged by the teeth or projections m onthe disk m. The disk m and spring n are included in an electric circuitindicated by the wires 0, 0', said electric circuit extending to acentral station where it includes an instrument of suitableconstruction. From this construction it will be seen that when the-diskm is permitted to rotate by the operation of the device the projections-m' will successively engage the springn and thus make and breakthe electric circuit, and thus cause the instrument at the centraloffice to report the number of the box operated.

A lever 19 is pivotally connected to the under side of the disk g, andis provided with an arm 0' which, when the parts are in position to beoperated, engages a spring 19 secured to the frame 9 The lever 19 isguided in its movements by means of a pin 9 pro-' jecting through anelongated slot p in the disk g. On the inner face of the lever 19 ashoulder q is formed, with which an arm q projecting from a collar (1fixed on the shaft or arbor g is adapted to engage when the parts are inposition to be operated. An arm 4" projects from the collar (1 and ispreferably made in the form of a segment. At one end of the segmentalportion of the arm r is a projection r, with which a pin r on the makeand break disk engages to limit the movement of said disk. In order torelieve the strain on the pin r byits constant and sudden engagementwith the arm 'I', a spring or yielding device s is secured to the frameg and adapted to receive the end of the projection r of the arm r, saidprojection reaching the spring 5 slightly in advance of the pin r on themake and break disk. I

Now let it be supposed that the clock movement has been brought to astandstill and the operator wishes to manipulate the device. He graspsthe crank arm h and causes a partial revolution of the disk g. By thismovement of the disk the spring of the clock movement will be partiallywound up and the arbore to which said spring is attached will be rotatedthus raising the arm a out of engagement with pin 6 and thereby releasethe clock work. When the disk 9 is in position to be operated (andbefore it is rotated as above mentioned) the spring 19 is in engagementwith the arm p of the lever pand retains the shoulder q in engagementwith the arm q projecting from the collar g Now, suppose the disk to bepartially rotated as above described. It will be seen that the clockmovement will be set free asabove mentioned and that the shaft or arborg will be rotated and the spring j wound up. When the disk shall havebeen rotated sufficiently the end of the lever 19 will engage a stop Ifsupported by the frame g and thus be moved away from the arm q,therebyreleasing the spring j and the parts which it actuates. Thus it will beseen that the make and break mechanism will be set in motion and thesignal turned in. The clock movement will now continue its operation andas'it operates the disk d will be moved slowly to the starting point, atwhich time the clock movement will be again stopped.

A sliding bar to is connected to oneside of the frame of theclock-movement and, provided with elongated slots u, for the passage ofthe pins or screws which support it. An arm 20 projects downwardly fromthe sliding bar u and at its lower end is bent so as to lie normally, inthe path of a pin a projecting from the under face of the disk d. Inproximity to the upper end of the sliding plate u,

when the device is operated to set the make and break mechanism inmotion, the pin a projecting from the disk will strike the arm a of thesliding plate u and thus start the clock movement.

In operating the device, the watchman will grasp the crank arm h andcause a partial revolution of the disk J. The disk g being connectedwith the winding arbor of the clock movement, by the pitmanfand arm f,when the disk g is turned as above explained, the winding arbor willalso be turned and thus the spring of the clock movement will be wound.When the winding arbor is thus turned, the end of the L-shaped arm awill be moved up, outof engagement with the pin c projecting from thewheel or pinion (I, thus releasing the clock movement. When the disk isturned by the watchman as above explained, the pin a on the disk g willstrike the arm 102 projecting from the bar it and cause an upwardmovement of the latter. Then the bar to moves up, the spring arm 21;carried thereby, will strike the escapement lever a and set the clockmovement in motion. The clock movement will run for one-half hour, whenit will be stopped by the engagement of the L-shaped arm c with one ofthe pins c on the pinion a. During the operation of the clockmovement,thepointer-i will move from one figure on the dial 2' toanother, the figures on said disk counting, as above stated, byhalf-hours. At each revolution of the disk 0 on the shaft a, the tooth con said disk will engage one of the notches in the disk cl and cause amovement thereof,the figures on said disk indicating the days of theweek, as above described.

\Vhen the disk g is turned to produce the operation of the clockmovement above mentioned, other devices will be set in motion, wherebyto operate electrical signaling mechanism, the operation of whichmechanism is as follows: When the disk g is turned by the watchman, thearm g carried by the shaft or arbor g will engage the shoulder g on thelever 19 and thus cause said arbor to move with the disk g and wind thespring j, the shoulder q of said lever 12 being retained normally inengagement with the arm g by means of the spring 13 When the disk g andits arbor g shall have been moved to a suflicient extent, the forwardend of the lever 19 will engage the pin or stop tand byit will be movedout of engagement with the arm q, thus releasing the arbor g from thedisk g, whereupon said arbor will be rotated by the spring j and causethe operation of the electrical make-and-break mechanism, in a mannerwhich will be presently explained. The disk g will be returned to itsnormal position by means of the clock movement, through the medium ofits connection therewith and when it reaches its normal position (whichrequires a half hour), the shoulder on the leverp will again engage thearm q. Thus it will be seen that the device cannot be operated oftenerthan each half hour. In other words the watchman cannot turn in thesignal before the prescribed half hour has expired. When the arbor g andthe disk propelled thereby have been rotated sufficiently by the springthey will be stopped by the engagement of the segmental arm r with thepin T In order to prevent the breakage of the pin 1' by the sudden orabrupt engagement of the segment 0', the spring arm or yielding device 5is employed.

\Vhen the shaft g is rotated by the spring j as above explained, motionwill be imparted,

through the gearing above described, to the make-and-break disk m,causing its teeth or projections m to ride over the spring p and thusmake and break the electrical circuit which includes said disk andspring-thereby operating the signaling amiaratuslocated at a centralstation.

From the construction and arrangement of parts as above described itwill be seen that it will be impossible for a watchman to operate thedevice until a certain predetermined time has expired. The hand orpointer will indicate the number of signals turned in, which willprevent watchmen and operators at the central station from workingtogether and giving false reports. The reportcoming in from the centraloffice must tally with the indicator on thetime movement. By this meansa report is had from the clock movement and also from the centralofiice, thereby watching both watchman and operator at the centralstation. In a building where a number of time detectors are employed, itis not necessary to provide more than one with the make and breakmechanism, as all the indicators must tally with the one having the makeand break mechanism.
